Checkmk vs Watchlog

Checkmk monitors cloud, hybrid, and data center infrastructure, including containers and networks. For web, mail, and database servers, it combines more than 2,000 smart checks with automatic discovery and network mapping. Monitoring can use native agents for Windows, Linux, and other systems, agentless SNMP and TCP/UDP checks, or API-based checks over HTTP/XML, SSH, or TELNET. Cloud coverage includes AWS, Azure, and Google Cloud Platform, with automatic component detection and Quick Setup. One instance can monitor thousands of servers, while distributed monitoring supports horizontal scaling. Community includes more than 2,000 integrations and is intended for smaller environments, scaling to approximately 100 hosts. The software can run on customer hardware or virtualized infrastructure, with Linux distribution packages, Docker, and a Virtual Appliance. The Community plan is free forever and includes community support. The pricing note lists paid plans from €190/mo (annual) and a 30-day trial. Other listed plan prices use USD: Pro is $275 a month, Cloud is $290 a month, and Ultimate is $400 a month. Platforms include API, Linux, macOS, self-hosted, web, and Windows.

Watchlog combines infrastructure metrics, logs, distributed traces, real user monitoring, uptime checks, synthetic journeys, integrations, AI analysis, and alerting in one observability platform. Its agent collects host metrics such as CPU, memory, disk, network, load, and processes. Log monitoring provides full-text search, real-time alerting, and log-to-trace correlation. API checks support multi-region HTTP monitoring, response validation, latency and SLA tracking, and SSL certificate expiry monitoring. Alerts can route to Slack, Telegram, and webhooks; integrations include MongoDB, PostgreSQL, MySQL, Redis, Elasticsearch, Docker, Kubernetes, NGINX, IIS, PM2, and GitLab. The Free plan includes one monitoring agent, one API check, 10,000 custom events per month, limited log storage, and a basic dashboard. Pro costs $4.99 per month, billed with usage-based add-ons, and includes unlimited agents, up to 50 API checks, and full APM, RUM, and log monitoring. A 30-day trial is offered without a credit card to begin.
